If you can't get all the way to the Flattop parking lot there is a road like Aurora View or something like that. On your way to Flattop it will be on your left. It ends in a circle but it is surrounded by trees so once you have found the end come back a little So, try Flattop, if the parking lot is close or snowed in and you feel comfortable just stay on the street outside of the parking lot. If not head to that Aurora road.

Use a tripod, keep your ISO low to capture detail and go with a long exposure. I saw one guy use an iso100 with a 30-sec exposure

Yep that's where I went. Ended up having a camera malfunction as the focus lens decided to pop off. I wasn't about to try and get it back in place on the mountain. Its back in place and will try again tonight. Yesterday was a 4 rating tonight is a 5.

Did you see any aurora? Those are nice of Flattop but you are looking South/Southeast. There looks like there may be some color on Flattop like it may have been reflecting something behind you, maybe city lights, maybe aurora. Good luck tonight. spaceweather.com says it hasn't hit yet
